title: Validation of the Danish version of the Oxford Elbow Score.
abstract: BACKGROUND
  The Oxford Elbow Score (OES) is a patient-related outcome measure quantifying quality of life in relation to elbow disorders. This 12-item patient-administered English questionnaire comprises three domains: function, social-psychological status and pain. The purpose of this study was to examine the structure and reliability of the Danish version of the OES (D-OES).
  
  
  METHODS
  A total of 130 patients who had total elbow arthroplasty (TEA) surgery performed in the period from 1981 to 2008 completed the D-OES. The Disability of the Arm, Shoulder and Hand score (DASH) and the Mayo Elbow Performance Score (MEPS) were also completed with a view to examining the convergent validity of the D-OES. In 45 cases, the questionnaire was completed twice to allow for calculation of test-retest reliability. The structure of the questionnaire was tested using Rasch analysis.
  
  
  RESULTS
  Overall internal consistency tested by Cronbach's alpha was 0.99. The test-retest reliability correlation coefficient was 0.99. Expressed in terms of Pearson's correlation coefficient, the convergent validity of the D-OES's functional, social-psychological and pain domain was 0.78, 0.80 and 0.81, respectively, for the MEPS and -0.66, -0.58 and -0.49, respectively, for the DASH. The 12 items of the D-OES fitted the Rasch model, and the multidimensionality of the OES was confirmed.
  
  
  CONCLUSIONS
  The Danish 12-item OES is a valid and reliable-patient administered questionnaire that can be used to quantify quality of life in patients with TEA.
